In JDK 1.1, both the List & Choice components had their removeAll()
method implemented as looping through the elements associated with
the component, and removing each element separately.
For large (or frequently updated) components, this takes significant
UI refresh time.

In JDK 1.1.2, the removeAll() method for the List component has been
reimplemented to perform a clear() within the Peer code.

We need the same change applied to the Choice component, in order
to see acceptable refresh time.
